thirsty patrol

gday robert.
i have asked plenty of people at work about the kays there getting from there gas and most would say about 400-450ks to a tank 90ltr.so your somewhere close as for the roof rack if i leave mine on it costs me about 70ks to a tank so it will make it worose.new job coming so no fraser this time:-((

Hi Robert,

I have a SWB GQ TB42 on lpg/petrol.

On average I'm getting get around 20-25lt/100km between the two fuels depending on the type of driving.

Petrol is slightly better than gas, and a roof rack will make a difference.

Cheers,

Luke.

Hi Robert
Mine varies between 23 to 25 L/100 on petrol and 25 to 30 L/100 on gas, depending very much on conditions (chewed through 34L/100 once towing a Jayco through heavy sand with air con on).

Don't bother trying to get any better - I have been trying for years, even after a full recon job with fully balanced motor, carby overhaul, dizzy overhaul etc. etc. made very little difference. I too run a full rack and quite a bit of weight.

Just rest assured that at least it will go close to forever...

Cheers
Gerry

Have you had it serviced lately? Start there, Dual fuel GQs NEED regular servicing. It makes a LARGE difference... Full Tune and Service. If in Melbourne, call Rod McCormack at TOtal 4wd Center in Epping. VERY HIGHLY RECOMMEND.

Roofracks=parachutes=bye bye fuel... Throw it in the shed unless you REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY REALLY need it.

What tires are you running? Also makes a difference. Is your car stock, or lifted, etc?? What accessories do you have, EG Whats the weight of the Vehicle?

Every GQ owner goes thru this on Dual Fuel, Luke that posted above nearly had heart failure on his first trip with us in his Petty/gas GQ up to Mt SKene!

He had it serviced by Total 4wd center, and is a little happier (Coming from a 2.8 GU), apart from the clutch dying, the head falling apart like all TB42 LPG GQ's, and the welch plug on back of motor dying in the bumhole..

$3000+ so far on top of purchase price and none of it really on mods, just maintance!!!!

I had a 1990 (nearly 1991) ST GQ on dual fuel and I ended up getting 4.6km per litre. You're getting 3.79 km/p/l - which is about where I started from.

There were a few mods made which if I didn't need the extra range for a particular desert trip, i wouldn't have bothered with. ie cost/benefit = RS.

Ah Robert they are thirsty - but its a great carby - never let you down - even when you are near vertical. The 4.2s even in the EFI version never vary much on fuel consumption.
The 3 lits have a lot going for them can get over 13lit/100km (21mpg) on a trip but usually 18lit/100km (15 mpg) around town. They are no slouches either.

Best thing if you are keeping it is to put in a LR tank, tune it, fit extractors and a 3" exhaust and use slightly larger overall diameter tyres (It wont notice the extra diameter except on very steep downhill runs in low 1st - there is heaps of power there - unlike a diesel)
This will all cost more than you will save in fuel in the 1st 3-4 years. But hey you must have got her for the right price so you still come out in front over a newie.

ROBERT,

Get ya points checked, GQ's are deadly on them especially on Gas, I had a 91 Mav, (which looked remarkably like a GQ, but it was a Ford) ate points for brekky and when the economy went down the points were the culprit. My economy varied from 18l/100km to 40l/100km so don't despair! Its not your GQ alone.

C whatya reckon

All the bestSo many places to go!
So much work to do :0(

I had 90 Patrol petrol back in 95, you could almost watch the fuel gauge needle
heading towards empty, there is only one solution for vehicles over a certain size & weight... DIESEL. I know this dosn't help your problem Robert but big vehicles on petrol are thirsty.

Heres an Idea.

Piranha GQ Electronic Ignition

This is a complete kit that replaces the points arrangement in the dissy. A small cutter wheel and sensor sits in the dissy and a small sealed control box is mounted in the engine bay. Then its just a matter of connecting to the coil.

Electronic ignition will let the motor run and rev out smoother. It is also more reliable as there is no problems with burning out points or adjusting point gaps.

I'm building an electronic ignition for my car as we speak.....will post results at a later time :-)

i got a 93 model GQ Lpg/Petrol with 110L LPG tank and 90L petrol tank. I get between 370 to 400kms out of both.

I tested this on a recent trip and managed to go 780kms between both and this was before the LPG gauge showed red. I also have bullbar and roof rack and was also carrying the usual gear for a long distance camping trip so i was happy with that considering the weight that was in the car.

In the city i usually get about 350 - 370km but then most of my driving to and from work is freeway related.

regards
Jeelan
